An Erlenmeyer flask, commonly known as a conical flask or E-flask, is a widely used type oflaboratory flask which features a conical base and a cylindrical neck. They are usually marked on the side (graduated) to indicate the approximate volume of their contents. It is named after the German chemist Emil Erlenmeyer, who created it in 1861.

Function of conical flask?
A conical flask is commonly used in laboratories to hold and mix liquids. It has a narrow neck to prevent splashes, and the conical shape allows for easy swirling and mixing of solutions without spilling. It is also commonly used for titrations and other chemical reactions that require controlled mixing and observation.
What is conical flask accuracy?
A conical flask is typically used for holding and mixing liquids in a laboratory setting. Its accuracy in measuring volumes is limited, as it lacks precise calibration markings like those found on a graduated cylinder or volumetric flask. For more accurate volume measurements, a more precise measuring device should be used.
What is the maximum amount of liquid that a conical flask can hold?
The maximum amount of liquid a conical flask can hold is determined by its capacity, which is typically around 1 liter. However, you should avoid filling it to the brim to prevent spills and ensure accurate measurements.
Why is the conical flask only rinsed with distilled water in the titration procedure?
The conical flask is rinsed with distilled water to ensure that there are no impurities or residues that could affect the accuracy of the titration results. Using distilled water helps to avoid introducing any additional substances that could react with the titrant or interfere with the reaction being measured.
What is a flask used for?
A flask is a type of container often used for carrying and storing a small amount of liquid, especially alcohol. It is typically made of metal or glass and has a narrow neck for pouring. People use flasks for portability and convenience when traveling or attending events where beverages may not be readily available.
